I can't say I really enjoyed the film as a whole all that much, but I did enjoy certain scenes. The use of kite-suits as two ninja apprentices battle while climbing majestic mountains to gain the right to the title of "ninja" was amazing. Other than the scenes from Transformers: Dark of the Moon where squadrons of soldiers glide out of the sky, I'd not seen these suits used anywhere. But it was fun to see the final scenes in Norwegian Ninja as well as the raw footage in the extras to get a sense of the speed they were traveling at and how close they were to rugged mountain cliffs.
Included with DVD are many special features. The three deleted scenes are definitely unnecessary and a bit verbose in spots, so I could see why they were cut. The bonus scenes include quite a bit of extra footage that didn't make it into the film, including the kite-suits and footage of the explosions done. I actually preferred the clean footage to the tinted footage used in the film for most of these. Also included are six featurettes, including interviews with actor Mads Ousal (who plays Arne Treholt in the film), writer-director Thomas Capplen Malling, and producer Eric Vogel.
I anticipate that Norwegian Ninjas will become a cult classic to some people, especially if those folks like bizarre alternate histories. Perhaps if the writer-director Thomas Cappelen Malling had added a bit more obvious humor it would have stuck, but this film didn't do anything for me. Maybe next time.
